I suspect you must have the Auto virtual hosts setting unchecked as shown in image below:

If so, open hosts file by clicking the h on Laragon window :

accept the UAC popup:

Check that the opened hosts file contains the entry of the URL you are trying to connect.
If it's not there, then add the entry manually as shown in the image below by changing the youprojectname to your desired name.

Save the hosts file. Close it.

Reload the Apache/Nginx if required and see if this fixes your problem.
